, y'Be it knowny thatvwe, FRANK Rune' and WERNER RicKARDsoN, citizens of the United States', residing at Falk, in the county of Humboldt' and State of California, have invented new and useful Improvements in ,Recorders or Indicators, of which the following is a specification. j

The purpose of the present invention is theprovision of a device for .recording thel speed 'of-vehicles, variations'in the level ofi liquids and diierences in pressure of bothil yliquids yand fiuids and also to indicate the speed of vehicles such as automobiles, trains!` rand the like.

rovides a mechanism,` ,for recording the' particular time of the varifr ations of liquids or fluids and the speed of if jvehicles so that on reference to any required g tirne'the iiuid pressure or the speed may be ascertained. l The invention contemplates Ia time move-j; sment, a recording strip fed by the time f lmovement `and recording means actuated by the moving art according to the particu .lar purpose or which lthe mechanism is dei` signed. i`

The invention consists yof the novel feaf tures,- details of construction and combina| -tion of parts, which hereinafter will 'bel more particularly set forth, illustrated in'y 'the' accompanying drawings, and pointedi. out in the appended claim.

Referring to the drawings, forming a part of thel specification, Figure 1 is a front view@ of a recorder embodying the invention. Fig.} 'is a side'view of the mechanism, the near@ .side of the casingbeing removedand parte;` Ybeing broken' away.' Fig. 8 is a horizontal"I section on the line -w of'Fig. 1.

' :to in the following description, and indicated in 'all the views of the drawings, by

the same reference characters.

The mechanism yembodies. a casing 1 which 60 may be .of any suitable construction and desifgn, the interior being accessible by Vmeans o a door which is made secure by any ap proved lock device, thereby preventing tam pering with vitale.

A time movement 2 of .any make or vari'- aety is located within the casing 1- andis adapted :to operate` .the strip 3 upon which` the record is made. The time movementis selected. with a view of running a number ofV days without requiring rewinding. pulley thas connection with a rotating part r .of the timemovement to be operated thereby. The strip 3 passes over the pulley 4; and is fed thereby.- Two pulleys 5 and '6 are 75 located within the casing 1 preferably near f thelower end thereof. One of the pulleys,

as 6, has the strip `3 wound thereon andthe Aother pulley 5 is adapted to have the strip wind thereon vas the record is made. The pulleys 5 .and 6 are arranged in contact so that .thevpulley l'may be rotated by means .of the pulley 6 so as to wind the' strip 3 upon the pulley 5' as said strip iS--unwound from the pulley 6. -The pulleys 5 andY 6 are 85 mounted toadfmit of their quick removal and also to allow for variation in ldiameter. M

v.As the strip 3 is unwound from the pulley 6 the diameter of :said pulley decreases and the' diameter of the pulley 5 correspond- 90 ingly increases. The strip 3 is unwound .from the pulley v6 by means of .the positively s. 'driven pulley 4:, the strip 3 'being wound upon the pulley 5 by frictional contact .with the pulley 6.' Springs? engage the journals 95 or'ends of the shaft yof the pulley 6 .so as to press said pulley in contact with the pulleys.. 5.. The pulleys 5 and 6 are supported in .plates in which .are formed slots 8 and, the slots 8 kcurving-upwardly and the slots 100 9 extending .through the ends of the plates. 4The pulley .4 has ,grooves 10 op ositethe f o which .a record is .madeupon the strip To prevent l and to insure a .positive movement of tnestrip 3 the .pulley 4 lmay becovered p W-ithruhber .or may be provided with points f Itis preferred to provide two pointersll one indicatingthe direction of travel of? .a vehicle when moving in vone way and them()r l'other todesignate the direction when the vehicle-is moving theopposite way. The strip 3 may be ruled to indicate the hours and -ractional parts thereof so that the time of threaded shaft 17 is connected with the pulley 13 so as to rotate therewith and a nut 18 is mounted upon the threaded shaft 17 and is provided with the styli or pointers so as to move the latter over the strip 3` according to the direction of movement of the shaft 17. The shaft 17 may be moved by any mechanism dependent upon the par ticular use Jfor which the recorder is constructed. For indicating pressure a rack bar 19 is employed, the toothed part being arranged to engage a pinion on the arbor or the shaft provided with the indicating hand.

TWhen the recorder is designed for use in connection with a steam boiler it is proposed to combine therewith an alarm for indicating high and low water levels, the alarm circuit including contacts which are closed at the predetermined high and low levels so as to apprise the engineer or other attendant of imminent danger, thereby giving ample warning so that the abnormal condition may be remedied to prevent disastrous results.

lt is contemplated to indicate speed and to also record the speed of a vehicle at any time and in either direction.

Figs. 4 and 5 indicate means for showing the speed of the vehicle when in motion. lin

Fig. 4V a pointer 20 is moved over a scale 21 by means of a governor mechanism 22y of the weighted arm type. ln Fig. 5 .the pointer 23 is arranged to move over a scale 24, said pointer having a spoon or bowl 25 at one end to receive a blast of air created by means oil a blower 26, which is operated from a pulley 27 mounted upon a worm shaft which has connection with the moving part of the vehicle. 1t is to be understood that the blower 26,.-will be operated with a greater or less speed depending upon the speed of the vehicle, thereby creating a blast of greater or less strength so as to operate the pointer 23 and move the same against the tension of a spring 28, which adjustably connects the pointer with a part of the framework.

in the operation of the mechanism the strip 3 is continuously moved by means of the pulley 4, which is driven in the same direction by the. time movement. The strip is held smooth upon the pulley 4 by means of springs 7. As the strip passes over the- A float 14 is attached to one endv pulley 4 an impression is made therein by the pointers or styli 11, the end of the record being determined by the position of the impression upon the strip.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while 've have described the principle of operation of the invention, together with the device which we now consider to be the embodiment thereof, we desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claim appended hereto.

Figs. 6, 7 and 8 show a shaft 29 having a worm 30 meshing with a worm wheel y31 secured to a transverse shaft 32 which is provided with a pointer 33 and a hub 34 having oppositely disposed cams 35 arranged to engage two springs 36. Each spring 36 has a p'oint 11 which is adapted to engage the strip 3. rFhis form of recorder is for automobiles and analogous vehicles which travel in one direction only. The two springs 36 and cams 35 enable openings to be punched in the recording strip 3, since they operate alternately. In the event of backing the vehicle the cams 35 press downwardly upon the springs 36 without bringing the points 11 in contact with the recording strip, but when the vehicle is advancing the cams engage the under side of the springs 36 and lift the same a distance so that when they clear the cams the points 11 are brought into engagement with the recording strip to punch openings i therein.

1n the construction shown in Figs. 9,10 and 11 two springs 37 are oppositely disposed e'ach having a point 11 at its inner end andV provided with an inner extension 38, which is adapted to be engaged by means of a cam 39 secured to the shaft 32. This construction of recorder is designed for railway cars and like carriers ,which travel forwardly and backwardly. When the car is moving in one direction one of the springs 37 is elevated by the cam 39 and when clear ing said cam makes a record upon the strip 3 and the opposite spring 37 is depressed by the cam 39 without bringing the point 11 in contact with the strip 3. yllVhen the car moves in the opposite direction the operation is reversed, that is the spring 37 previously out of operation is caused to act to produce va record and the spring previously making a record is thrown out of operation.

The terminals of the alarm circuit are indicated at 40 and 41, the latter being connected with the frame and the conductor 40 having connection with a rod 42 which is electrically insulated from the frame and which has a, movable contact piece 43 to be engaged by a projection 44.- carried by the nut 18. The alarm circuit is chiefly designed for indicating danger in connection with high and low water level of boilers and high or low tides so that those engaged in the fishing industry may be advised as to the time when the tide reaches a given level.

Having thus described the invention what is claimed as new, is

In combination a recording strip, a spring having a marking point normally occupying a position to clear the strip, and a cam adapted to engage the spring in one direction to move `the point thereof toward the v Cam.

In testimony whereof we ailix our signa.- tures 1n presence of two wltnesses.
